Linker: Remove unnecessary call to copyMetadata in IRLinker::linkGlobalVariable. This was causing us to create duplicate metadata on global variables. Debug info test case by Adrian Prantl, additional test cases by me. Fixes PR31012. Differential Revision: https://reviews.llvm.org/D26622 llvm-svn: 286905
